South Africa and the 21st Century Power Partnership

May 2018This fact sheet provides an overview of the mission and objectives, and recent activities
for 21CPP work in South Africa.

Preliminary Findings of the South Africa Power System Capacity Expansion and Operational
Model Study

January 2018This state-of-the-art grid integration study examined the effects of potential high
penetrations of variable renewable energy on South Africa’s power system. To achieve
this, NREL developed, tested, and ran a combined capacity expansion and operational
model of the South African power system including spatially disaggregated detail and
geographical representation of system resources. New software to visualize and interpret
modelling outputs was developed, and scenario analysis of stepwise variable renewable
energy build targets provides new insight into associated planning and operational
impacts and costs.

21st Century Power Partnership: September 2016 Fellowship Report

September 2017This Fellowship is a follow-up to the “Technical Audit of Eskom’s Medium- and Long-term
Modelling Capabilities,” conducted by the National Renewable Energy Laboratory (NREL)
in April 2016. The prospect and role of variable renewable energy (vRE) in South Africa
poses new modelling-related challenges that Eskom is actively working to address by
improving the fidelity of PLEXOS LT and ST models.
